also the fine‐tuning of physicochemical and biological properties of drugs, agrochemicals and polymers. We report here a general and practical photochemical strategy enabling the site‐selective chlorination of sp3 C−H bonds. This process exploits the ability of protonated N‐chloroamines to serve as aminium radical precursors and also radical chlorinatingagents. Upon photochemical initiation, an efficient

The invention relates to a method for producing an aliphatic polyester, utilizing starch as a raw material. The invention produces an aliphatic polyester by the steps of hydrolyzing starch to obtain glucose, oxidizing the glucose to obtain gluconolactone or gluconic acid, reducing the gluconolactone or the gluconic acid to obtain caproic acid, chlorinating the caproic acid to obtain 6-chlorocaproic acid, cyclizing the 6-chlorocaproic acid to obtain &egr;-caprolactone, and executing ring-opening polymerization of the &egr;-caprolactone.
